Default Bug#637122: general: Realtek RTL8111 with r8169 module causes kernel panic on large packets

Package: general
Severity: normal

The kernel panics when it receives a packet on an interface running the r8169
module that is of sufficient size.

To reproduce, have another host on the interface with MTU of 9000 to send a
ICMP ping packet of size 9000, and then the driver will cause a panic. It seems
the crash depends somewhat on the MTU of the r8169 interface as well as
under some conditions there is no crash. I haven't had a chance to play around
with this much because my only machine to test this with is running our
file-server during business hours. Googling around seems to suggest that bugs
like this have existed before:

http://www.cvedetails.com/cve/CVE-2009-4537/

Is there any way to mitigate this problem? I can't exactly use my gigabit
network to the fullest when all the machines have 1.5k MTUs to prevent this
crash.

Which package version do you have installed?
(Run 'dpkg -s 'linux-image-2.6.32-5-686'.)

Also, you must send the panic messages. Use a serial console or
digital camera to capture them.

Default Bug#637122: general: Realtek RTL8111 with r8169 module causes kernel panic on large packets

Thanks Ben. My first bug report, so excuse the lack of info. :-)

This is a command you can run from the Windows command prompt to cause
the
crash (I believe the -l switch is equivilent to -s on unix, but I think
windows might handle ICMP pings a little different too)

ping -l 8146 serverhostname

This is most of the kernel panic. It scrolls away awfully fast and I had
to
change the resolution and font the screen was running just to get this
much.

I hope you guys can piece the images together.

Here's some additional info about my interfaces. I believe the MTU
setting
of the Realtek card is important to making this crash happen but I
haven't
tested too thoroughly.

eth0 is the Realtek r8169, lan is the bridge that eth0 is in.

This may be related to the proprietary Elo APR driver. Please test
whether this can be reproduced without that software loaded.

Default Bug#637122: general: Realtek RTL8111 with r8169 module causes kernel panic on large packets

I killed the eloapr processes (it's a libusb driver) and the kernel
panic
still occurred. It might have just appeared in the panic because it is
constantly using CPU time (a drawback of the APR technology) and
happened
to be busy at the time of the panic.

Please send the new panic message.

Default Bug#637122: general: Realtek RTL8111 with r8169 module causes kernel panic on large packets

Here, I used a gparted LiveCD to replicate this bug on an extra set
of hardware we have. It appears to use a newer kernel but the bug
persists.

Let me know if this is adequate information. It was enough of a hassle
to dig up the serial cables and null modem changers...

I don't think this is actually a bug in r8169. That is just
coincidental. The crash occurs when trying to handle IRQ 19, which
appears to have a null handler (which should be impossible). Can you
run 'cat /proc/interrupts' to find out what IRQ 19 is assigned to?

Ben.
